Do I take the plunge?

[porsmork]

Some really useful threads here about chicken keeping. I hope I don't repeat what's already been said. I am thinking about getting two small chickens for our garden, as pets and for eggs. Ds is 18 months and I'm a sahm, so we're at home a fair bit.
My questions are;
Garden is about 5x5m, and on quite a slope. Is it possible to keep them in that space? Pic attached. I was thinking about turning the border where the tent is into their run.
Does an eglu work on sloping ground? (The run?)
Are they very noisy? I'm in a suburban housing estate.
What is your daily routine with them?
Any tips for a novice? I'm going on a course to handle them and get as much info as possible, but the more tips the better!

They are great fun.
Very friendly if you handle them the firsts few weeks.
They make a mess.
They dig up the garden.

I have a wooden coop. Ihave three,started with four, and mine are ex battery.
One clucks loudly when she has laid.
A course is a great idea. I really enjoy having them and the eggs are delicious. I am getting three a day at the moment. I had one to two in winter.

I now have three Pekin bantams! They are lovely, and much easier to clean out than I thought! Really pleased to have done it!
